What was wrong with the original CK no-thread headset? Just curious because I thought these lasted pretty much indefinitely.

Also, if you are thinking you want to do the work yourself you could get started by knocking out the old headset cups from the head tube. Once these are out you will get a better idea of the condition of the head tube & how accurate the internal diameter is.

Can I ask how much the Chris King 1” no-thread set sells for these days? If I were to guess I imagine that’s like a $240 part in today’s economy.
